Malocclusion is a deviation from normal relationship between the maxilla and the mandible while in centric occlusion. Classifications:

Model 3 Class II (division 1): The anterior relationship: maxillary central incisors are upright or retruded and lateral incisors are tipped labially or overlap the central incisors with deep over bite.

Model 4 Class III: Molar relationships: mb cusp of the maxillary fisrt molar occludes distal to the mb groove of the mandibular first molar. Anterior relationship: mandibular incisors are in complete cross bite. A cross bite is where the maxillary teeth are positioned lingual to the mandibular teeth.
